Ec250 balance shaft

Hi all
I need a little help with a 1997 ec 250 engine
I got it from a pal in a box in bits
The only concern i have is balance shaft parts
Does anyone have schematic of balance shaft as i need to know if it has thrust washers/spacers and position
Many thanks for any help

Here is a jpg of the crankshaft assembly and the CB shaft assembly of a 2003 Wild HP 300 Quad.
Next post will be the parts numbers and description for this photo.

Here are the descriptions and part numbers for the above post's attached photo.
All the ME256 numbers are the same parts used in the '97-'98 250 engines.

Take a close look at the attached picture.
Make sure the alignment dots on the two gears
match up.... Not like in the picture... This motor will
shake the crap out of the bike till you do.
I have a couple more pix if that might help.
